Cops believe that Savoia was drunk and accidentally fell off the boat, which was docked off 12th Avenue around 25th Street, law-enforcement sources said.

Savoia’s friend and longtime driver, Alberto Alonso — who reported him missing — said he got a call from an NYPD detective shortly before 2pm confirming that his boss’s body had been found in the river.

“What can I say?” a shaken, teary Alonso told The New York Post at his Queens home minutes after the heartbreaking call came in.

“I lost a good friend and a good brother today.

“I was hoping he was drunk and holed up with some supermodels,” Alonso said.

“Now I have to call his daughter and tell her. She’s 23, and I know she’s not going to take this well.”

Savoia — known as “Savoia the Tailor” — was famous for his handcrafted, retro suits and counted Robert De Niro, Ricky Martin, Mickey Rourke and Chris Noth as clients over the years.

The 182cm tall heavily tattooed designer was last seen leaving Chelsea club Marquee New York around 4am on Thursday, at the end of New York Fashion Week.

CBS New York quoted police saying that Savoia had been at a party thrown by Paris Hilton.

Alonso reported him missing on Saturday after failing to hear from him for two days, police sources said.

Friends became worried when Savoia didn’t show up for a Valentine’s Day dinner with a girlfriend. Savoia’s friends said he would sometimes disappear but would not stay out of contact for as long as he had last week.

The designer, who often wore a heavy fur coat, was feared to have fallen off his yacht after one friend noticed a side canopy was broken.
